In order to effectively seal the glass to the frame members, a head of putty has been placed around the perimeter of the glass adjacent all of the frame members. A variety of tools for achieving this purpose have been described in the past. For example, two such tools are shown in US. Pat. Nos. 2,247,603 and'2,247,604 (Christman July 1, 1941) Although putty application tools of this type may be useful in connection with such windows, experience has shown that they cannot be effectively used for more modern types of windows in which putty is excluded from one or more frame members. If conventional putty application tools are used on such a window, excess putty tends to be formed along the frame member from which it must be excluded, thereby necessitating removal of the excess putty by hand. This is a timeconsuming operation which generally leaves ragged edges and an undesirable appearance at the corner of the window. p

In order to overcome the deficiences of the prior art, applicant has invented a unique putty application tool which can accommodate windows having a continuous head of putty or windows having putty excluded from one or more sides of the frame by merely turning the tool upside down. When the bottom surface of the tool is adjacent the glass pane, intersecting chamfered edges form putty along both adjacent sides of a window frame so that a smooth continuous bead is easily formed,'even by a novice. Comating surfaces adjacent the chamfered surfaces contact the frame members to prevent putty from extending too far away from the glass pane. By merely reversing the tool so that its top surface is adjacent the glass pane, additional chamfered surfaces intersecting the comating surfaces can be used-to form a bead of putty adjacent one frame member while effectively excluding putty from an adjoining frame member adjacent a corner of the window frame. By this unique arrangement of components, the same tool can be used for accommodating any type of puttied window now commonly found in construction and putty may be applied to the windows with -a degree of ease and speed heretofore unattainable.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIGS. 6-11, a putty tool embodying a preferred form of the invention can be used in connection with a window 1 comprising a glass pane 2 that is supported by an upper frame member 4 having a planar side adjacent and perpendicular to the glass pane. As shown in FIG. 6, the window also comprises a left hand frame member 6 having a planar side 7-perpendicular to the glass pane. Frame members 4and 6 are arranged perpendicular to each other to form a square corner 8. As shown inFIG. 7, the window also comprises a right hand frame member 9 having a planar side which is perpendicular to glass pane 2. Frame members 4 and 9 are arranged perpendicular to each other to form a square corner 11. Window 1 can also comprise a lower frame member (not shown) which is parallel to upper frame member 4.

As shown in FIGS. 7-11, the window-can be constructed so that beads of putty 12 and 13 are .located adjacent frame members6 and 9, respectively, whereas no putty is-located adjacent frame member 4. Alternatively, as shown in FIG. 6, the window canbe constructed so that beads of putty are located adjacent each of frame members 4, 6 and 9.

Referring to FIGS. 1-5, a preferred form of putty application tool made in accordance. with thepresent invention comprises a planar top surface 16 and a planar bottom surface 18. that is parallel to and spaced /8 inch from surface 16. 'Planar chamfered surfaces 20 and 22 form identical obtuse angles with respect to bottom surface 18 and intersect to form an edge 24.

Planar comating surfaces 26 and 28 are each perpendicular to surfaces 16 and 18 and intersect at right angles to form a square corner that defines an edge 30 which is perpendicular to surfaces 16 and 18. The lower portions of comating surfaces 26 and 28 define edges 32 and 34 which lie ina median plane 36 that is half way between surfaces 16 and 18. Y

The tool also defines an up'per curved surface 40 tha is bounded on its lower side by aperipheral circular edge 42 that lies in medianplane 36. The circular edge has a center point 44 that is colinear with edge 30 and has a radius R of 3% inches. Surface 40 intersects with comating surfaces 26 and 28 to form edges 46 and 48, respectively. I

Curved surface 40 is bounded on the top by an upper circular edge 50 lying in top surface 16. Edge 50 has a center point colinear with edge 30 and a radius R1 of about 3 l [/16 inches.

The tool also defines a lower curved surface 54 that is bounded by peripheral circular edge 42 and by a lower circular edge 56 lying in bottom surface 18. Edge 56 has a center point colinear with edge 30 and a radius R2 equal to-about 3 '1 1/16 inches,i.e., equal to R1. Lower curved surface 54 intersects surfaces 20 and 22 to form edges 58 and 60, respectively.

The surfaces are arranged so that a plane Tl tangent to surface 40 at the intersection of surface 40 and surface 26 is parallel to chamfered surface 22. Likewise, a plane T2 tangent to surface 40 at the intersection of surface 40' and surface 28 is parallel to chamfered surface 20. Surface 40 makes an angle of about 1 18 with respect to top surface 16 and surface 54 also makes an angle of about 1 18 with respect to bottom surface 18. Charnfered surfaces 20 and 22, likewise, make angles of about 118 with respect to bottom surface 18.

Inorder to use the putty tool on a window of the type shown in FIG. 6 in which putty is formed adjacent each of the frame members, bottom surface 18 is placed adjacent glass pane 2 and edge '30 ismaneuvered into any corner, such as corner 8, so that chamfered surfaces 20 and 22 form a smooth bead of putty adjacent planar sides 5 and 7 of frame 'members'4 and 6, respectively. It should be noted that comating surfaces 26 and 28 contact and fit flush against planar sides 5 and 7 of frame members 4 and 6, respectively, to prevent putty from extending beyond the upper portion of chamfered surfaces 20'and 22, i.e. beyond edges 32 and 34. Edge 30 of'the tool can be maneuvered into each of the other cornersof the'window frame in order to achieve the same results shown in FIG. 6.

.In order to form a bead of putty along a straight portion of frame member, either the top or bottom surfaces can be placed adjacent the glass. Peripheral circular edge 42 is then slid along a frame member, as shown in FIG. 9, so that either surface .40 or 54. smooth'sthe putty into acontinuous head.

-In order to place putty on a window frame of the type shown in FIGS. 7 11 in which no putty is placed adjacent frame member 4, the tool is used in the manner shown in FIG. 9 with the top surface against the glass until a left-hand corner, such as corner 8, is approached. At this point, the tool is maneuvered into the position shown in FIG. 8 so that comating surface 6 lies flush against planar side 5 of upper frame member 4. The contact between the frame member and comating surface 26 prevents putty from being squeezed adjacent frame member 4. As shown in FIG. 7, the tool can be reversed to accommodate a right hand corner, such as corner 11, in which comating surface 28 is fitted flush against planar side 5 of upper frame member 4 to prevent putty from extending beyond corner 11' into contact with frame member 4.
